ihave a vbx30 which is giving an intermittent problem its had it since about 6 months old ive tried to get the plumber who fitted it to address the problem but he wont return any phone calls now the boiler is 18 months old and the problem has reared its ugly head again, if you turn on the central heating the boiler shows fault code d its not even mentioned in the bloody manual,to cure it i have to kill power to the boiler reset the heating and hot water controls upstairs go back down stairs switch power back on to the boiler go back upstairs turn it onto hot water,then turn on the heating and hope and pray the boiler lights up,if it goes into d mode its the same procedure again,this can sometimes take quite a few attampts other times it works first time,im getting towards the end of my tether with this and now really cant afford for somebody to fleece me as these things can only be done by corgi engineers any help would be greatly appreciated
